FABRIC OONSTRUCTED OF LAMINATED COHESIVE INTERWOUND Specification ofLetters Patent.

Application filed October 17, 1910. Serial No. 587,629.

To all whom it may concern:

Be it known that IfLAWRENCE A. Sunnns, a citizenof the United States,and resident of Cleveland, in the county of Cuyahoga and State of Ohio,have invented certain new and useful Improvements in Fabrics Constructedof Laminated Cohesive Interwound Members, of which I hereby declare thefollowing to be a full, clear, and exact description, such as willenable others skilled in the art to which it appertains to make and usethe same. 1

The objects of the invention are to provide a form of fabric which willbe possessed of great tensile strength, combined with great flexibilityand in which a minimum amount of rubbing or frictional contact of onefibrous member. upon another is obtained, on account of thepeculiarities of structure.

The fabric is composed of laminated-cohesive-interwound members whichare embedded in a vulcanizable binding material such as rubber, whichrovides flexibility without permitting the fibrous members to come intoactual contact with each other. The fabric is similar-in construction tothat described in my previous application Ser.

No. 540,982 filed January 31, 1910, in which a laminated,unwoven fabricis composed of a series of parallel equally spaced fibrous bands woundupon a mandrel at an angle of approximately to any longitudinal surfaceline upon which is wound or laid at an angle of approximately, 90 asecond similar'series of equally spaced fibrous bands, a third series ofsimilar bands is wound or laid thereon parallel to the first Famedseries in such a position as to cover the'spaces between the ands of thefirst series, and a fourth series parallel to the second series is woundor laid over all to cover. the spaces between the bands of the secondseries, thus forming an unbroken two ply sheet of fabric, withoutweaving, braiding, interlacing, or interlock; ing of the bands.Theseveral series thus wound are pressed together so that all therectangular openings between the bands are.

closed and the edges of one series of bands will engage the edges of theother parallel series of bands so that one series of bandswill not slipor slide over another. In this manner'a two ply fabric is formed,although .it may be made of any plural number of series and can mostreadily be formedby Patented Apr. 23, 1912.

shown and described in my said application.

The bands of the fabric'hereinafter described arev preferably composedaltogether or in part of cords, threads or yarns having a predeterminedamount of twist and are designed to be more flexible and to have lessfrictional action on each other and to beless liable to rupture,abrasion or disintegration from use or age for the purpose designed thanthe bands described in my former application in which twisted cords orthreads or woven reinforcing bands were employed. In this fabric thebands are shown interwound in a two g oup system and a four groupsystem, and each band may be reinforced with, or inclosed in an openmesh fabric, which has the double function of binding. the cords orthreads composing the material in close engagement with the bands meshfabric which are filled with this binding and adhesive materiaL.

The several forms of construction and arrangement of the various fibrouselements and binding material composing the bands is hereinafter morefully described, shown in the accompanying drawings and specificallypointed out in theclaims.

In the accompanying drawings Figure 1 is a plan view of the fabric,formed in a 160111 groupv system, from wo'und bands .formed oflongitudinally directed threads or yarns, the threads in each band beingunited by means of the rubber in which they are embedded; Fig. 2 is anisometrical perspective view of the same showing the bands" in theirrelative positions prior to being pressed together; Fig. 3 is a planview of a band broken away to show the outside coating of rubber and alayer of openmeshed netting between layers of thread, and F g. i is alongitudinal section of the same; Flg. 5 is a plan view of a similarband showmg a rectangular net intermediate between layers of threads,and an outer rubber coating; Fig. 6 is a longitudinal section thereof;Fig. 7 is a transverse section thereof en larged; Fig. 8 is a plan viewof a fabric formed in a-two group system from parallel,

.75 band together and of retaining the bindingequally spaced interwoundbands composed of twisted cords and having threads filling thelongitudinal depressions between these cords; Fig. 9 is an isometricalperspective view of the same; Fig. 10 is a transverse section of thesame enlarged; Fig. 11 is a plan view broken away and showing a band ofthreads having open mesh or reticulated fabric adhering upon each sideand an outer rubber coating; Fig. 12 is a longitudinal section thereof;Fig. 13 is a transverse section thereof; Fig. 14 is a plan view, brokenaway, of a similar band of threads but modified by having the open meshfabric on one side only of the threads; Fig. 15 is a longitudinalsection thereof; Fig. 16 is a transverse section thereof; Fi 17 is aplan view broken away to show a band of adhering twisted cords with alayer of open mesh fabric on each side thereof: Fig. 18 is alongitudinal section thereof; Fig. 19 is a transverse section thereof;Fig. 20 is a plan View of a band of longitudinally directed twistedcords, broken away to show a single covering of open meshed fabric and arubber outer covering; Fig. 21 is a longitudinal section thereof; Fig.22 is a transverse section thereof; Fig. 23 is a plan view broken awayof a modified form in which a band of cabled thread is entirelyenveloped in an openmesh fabric of hexagonal mesh, the edges of whichoverlap upon the band; Fig. 24 is an edge view thereof; Fig. 25 is aplan view of a similar band enveloped in an open rectangular meshfabric; Fig. 26 is a transverse section thereof; Fig. 27 is a plan viewof a band of twisted cords broken away to show two covers of open orreticulated fabric the edges of which extend beyond the band and adheretogether; Fig. 28 1s a transverse section thereof.

. In these views 1, 1 are bands composed of adhering yarns. These yarnsare laid in rubber or completely coated with rubber which binds themtogether. The yarns are laid in a parallel longitudinal direction andthey have the great advantage of being extremely flexible and not liableto rub upon and abrade each other when the fabric is put to use. Therubber serves to cause the yarns to adhere closely together and alsoseparates them out of actual contact with each other. The manner ofapplying the rubber or other adhesive material is not a part of thisinvention and may be accomplished in any manner which. will thoroughlyincorporate the rubber among the fibers. These bands are laid in rubberor equivalent adhesive vulcanizable binding material and cohere togethertherein, but are not interlocked in any manner and without the adhesivebinding material would quickly fall apart. The binding material entirelyincloses and separates them from actual frictional contact with eachother.

In Fig. 1 four series of parallelbands of yarns 1, 1, are shown crossedby four similar series in the reverse direction the memmembers of thebands together.

bers of each series being spaced four band widths apart, and the eightseries wound in succession a series in one direction alternating with aseries in the other direction to form a four group system of two plyfabric. In Fig. 2 this arrangement is clear and shows the bands 1, 1,before they are pressed together so as to fill all the openings. In thestructure shown in Figs. 8 and 9 the bands of each series are spacedonly one band Width apart to form a two ply fabric of'a two groupsystem.

In Figs. 2, 3, 4, 5, 6, and 7 a layer or strip 2 of open mesh orreticulated fabric is shown inclosed between two layers of threads. Inmaking the bands from threads or yarns a predetermined number isemployed according to the width and thickness of the band required. Thespaces or openings between the meshes are completely filled with rubberand hence the mesh serves to retain and bind the rubber coating withinthe band and provides a protection for the rubber as well as serving tohold the threads closely together 'and to prevent them from spreadingapart. 3 is an exterior rubber coating.

In Figs. 11,12 and 13, two layers 2, 2, of open mesh fabric are shownone on each side of the band of threads, thus retaining the coating 8 inplace, and aiding the adhesive material in binding the threads together.In Figs. 14, 15, and 16 one exterior layer of open mesh fabric 2 isshown.

In Figs. 17, 18, and 19 a band of twisted cords 0, c, adhering togetheris shown and two outer bands or strips of open mesh fabric embedded inrubber. In Figs. 20, 21, 22 only one strip of open mesh fabric is shown.In Figs. 23, 24, 25 and 26 the open mesh fabric is shown enveloping thesides and edges of the cabled thread bands. The edges of the open meshfabric overlap at P upon the sides of the bands and are cementedtogether in the rubber binding material. In Figs. 27 and 28 the openmesh fabric is shown on both sides of a band of twisted cords adheringtogether and the edges e of the fabric extend beyond the edges of theband and adhere together, thus inclosing the band.

I do not limit myself altogether to the exact arrangement of bands andopen mesh fabric or to the exact character of fabric employed to incloseand bind the fibrous It is essential however that the open mesh fabricshould not interfere perceptibly with the flexibility of the bands andthat this fabric should bind the fibers together and retain the rubberin close contact therewith.

In Figs. 8, 9, and 10, the bands are shown formed of longitudinallydirected parallel cords a, a, coated with rubber 3, and cabled threadsIf, t, are shown filling the interstices between the cords and embeddedin the rubber, thus reinforcing. the rubber and assistfabric, a rubberbinding material in which,

ing it in separating the cords out of frictional engagement with eachother. It isv obvious that to arrive at any predetermined thickness andWidth of the band of yarns or threads they may be impregnated with orembedded in the rubber binding material or other adhesive material andpassed through suitable forming rolls for the purpose intended.

"Having described the invention what I claim as new and desire to secureby Letters Patent is 1. In an unwoven laminated fabric formed ofcohering equally spaced fibrous I bands crossing each other to form atwo ply material filling the interstices in said open mesh fabric.

' 2. In a fabric, series of equally spaced parallel bands of threadscohering together,

and laid in one direction, to form spaces and series of similar bandsinterlaid in alternately parallel and crossing layers therewith to forma ply fabric, and a fibrous binding means for the threads in each band,a

each band having a binding of rubber incorporated therewith andall bandscohering together and compressed to fill all spaces between said spacedbands.

In testimony whereof, I hereunto set myt hand this 14th day of October1910. 4
